15 years ago I watched my brother buy a 1917 30-06 in the parking lot of a gun show for $35.
The barrel wants a 303 bullet.
MacFarland's gunsmithing book devotes all 35 pages about sporterizing to the 1917:

This is my 50th year of sporterizing Mausers.
It is never worth it.
You have to want to do it.
